Embodiment
Below in conjunction with the accompanying drawings and specific embodiment is described in further details the utility model：
The utility model discloses a kind of self-locking type safety door, which is used for workbench, can automatically reply
Closure state, security are good.
The self-locking type safety door of the utility model is arranged on workbench, and workbench edge sets railing to protect worker
Safety, and the convenient disengaging workbench of handrail door 1 is set.Handrail door 1 and the platform railing 2 of platform edges are hinged, by turning
The dynamic opening and closing for realizing handrail door 1.Some hinged seats 3 are fixedly installed on platform railing 2 in the utility model to be used for handrail door 1
Articulated connection.The axis order arrangement spaced apart of hinged seat 3 along railing.Hinged seat 3 to the greatest extent may be used to set the plate of circular hole
The concentricity of the circular hole of the guarantee hinged seat 3 of energy, to facilitate installation handrail door.Hinged seat 3 generally using weld by the way of and column
Bar 1 is fixedly connected, and hinged seat 3 generally sets 2~3, and concrete structure is as shown in Figure 1 and Figure 2.
Base sleeve 5,5 top of base sleeve is being fixedly installed in the utility model on the lowermost hinged seat 3
Inclined plane is set, and base sleeve 5 is general to be also fixedly connected by the way of welding with hinged seat 3.It is corresponding, cut with scissors in handrail door 1
The lower end for connecing end sets lifting casing 6, and the lower face for lifting casing 6 is set and 5 top inclination angle of base sleeve is consistent inclines
Inclined-plane, two inclined planes cooperate.The inclination angle of the inclined plane is traditionally arranged to be 25 °~30 °, and it is good to ensure that handrail door has
The performance being automatically closed, while ensure open handrail door will not be laborious.The utility model is in specific implement, handrail door 1
It is made of pipe fitting connection, lifting casing 6 is preferentially arranged to be integrally formed with the pipe fitting of 1 hinged end of handrail door.Concrete structure
As shown in Figure 3.
After hinged seat 3, base sleeve 5 are installed in place, the hinged end of handrail door 1 is passed through to the circular hole of hinged seat 3, most
